In this paper the unsolvability of generalized inverse eigenvalue problems almost everywhere is discussed.We first give the definitions for the unsolvability of
The purpose of this paper is to study the stability and approximation properties of Ritz-Volterra projection. Through constructing a new type of Green functions
Let A be an n×n real symmetric matrix. A is called completely positive (denote A∈CP_n) if A=B’B for some m×n nonnegative matrix B where m is an inte
In this paper, we prove that the chord method and the modified chord method are also convergent to the solution x<sup>?</sup> of F(x)=0 if the dimension of the nu
